Method for expressing haptic information using control information, and system for transmitting haptic information

摘要

Provided is a method for expressing haptic information using control information, and a system for transmitting haptic information. In the method for expressing haptic information using control information, a tactile video is generated from tactile information for driving a drive array of a tactile device; force feedback data are generated from force feedback information for driving an actuator of a force feedback device; object data are generated to produce a scene descriptor that defines time positions of the tactile video, force feedback data, and multimedia information; and a stream file is generated by encoding the object data and multiplexing the encoded object data. The method comprises: a step of storing control information containing features and specifications of a haptic device including the tactile device and the force feedback device; and a step of expressing information of the scene descriptor through the haptic device with reference to the control information.

1. A method for expressing haptic information using control information comprising:
generating tactile video from tactile information for driving a driver array constituting a tactile device, generating force feedback data from force feedback information for driving an actuator constituting a force feedback device, generating object data to produce a binary format for scenes (BIFS) that sets up time locations of the tactile video, the force feedback data, and multimedia information, encoding the object data, generating a stream file by multiplexing the encoded object data, storing the control information and user preferences, wherein the control information contains features and specifications of a haptic device, which is comprised of the tactile device and the force feedback device; performing resizing of the tactile information and/or the force feedback data based on the control information, wherein the user preferences have priority over the control information, and expressing information of the BIFS through the haptic device with reference to the control information.
